    (54) Vibratory gyroscope


    (57) A vibratory gyroscope comprises, for example, a regular triangular prism-shape vibrating body (12). On the center portions of three side faces of the vibrating body, piezoelectric elements (14b) are formed. A connecting lead (26b) is soldered to each of the piezoelectric elements. Outside vibrations transmitted by the leadwires to the piezoelectric elements is damped by the application of a strain relieving elastic adhesive (28b) to each of the soldered joints.
